Table 6 Predictors of 12-month changes in health-related quality of life (measured by SF-36)

From: Dietary weight loss and exercise interventions effects on quality of life in overweight/obese postmenopausal women: a randomized controlled trial

	12-month changes in HRQOL
	Physical functioning		Role-physical		Vitality		Mental health
	β	P	β	P	β	P	β	P
Change in weight	-0.50	< 0.001	-0.67	0.001	-0.74	< 0.001	-0.15	0.04
Change in aerobic fitness	4.67	0.01	3.65	0.37	0.93	0.65	-0.15	0.91
Change in depression	-0.12	0.10	-0.50	0.001	-0.42	< 0.001	-0.43	< 0.001
Change in perceived stress	-0.58	0.02	-0.66	0.24	-0.79	0.004	-1.28	< 0.001
Change in social support	0.17	< 0.001	0.24	0.01	0.08	0.07	0.04	0.18

The regression models were adjusted for group assignment, baseline health-related quality of life (HRQOL) scores, and covariates (Physical functioning: baseline BMI, medication use, Role-physical: age, baseline BMI, Vitality: age, medication use, Mental health: medication use)
